How can we apply population models to real world data?
Answer:
use mathmatical representation to support explanation of factors that efect carrying capacity of ecosystems at different scales as support and revise evidence about factors affecting bio-diversity and populations in ecosystems of different scales
Explanation:
Population models have been used to analyze and study population dynamics. It can be applied to real-world data to understand the carrying capacity of the ecosystem and factors affecting biodiversity.
What is carrying capacity?The carrying capacity of the ecosystem is defined by the number of individuals or the population that can be entertained in a specific geographical area at a particular time.
The carrying capacity, population dynamics, biological invasions, conversation, and biodiversity can be explained by the population model.
The model describes the mechanistic and mathematical representation that allows a better understanding of dynamics and statistics. This is applied in the real world to understand the carrying capacity of the ecosystem.
Therefore, the population model can be used to analyze the carrying capacity.

Hydrophobic substances such as vegetable oil are *
1 point
nonpolar substances that repel water molecules.
nonpolar substances that have an attraction for water molecules.
O polar substances that repel water molecules.
O polar substances that have an affinity for water.
Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.
What are non polar substances?Nonpolar substances are molecules that do not have a charge separation between different parts of the molecule. This means that they do not have a polar, or electrically charged, end, and as a result, they do not dissolve well in polar solvents like water.
Nonpolar substances are hydrophobic, meaning that they repel water molecules, and tend to dissolve in other nonpolar substances, such as oils and fats. Examples of nonpolar substances include hydrocarbons like gasoline, fats, oils, and waxes, as well as some gases, like nitrogen and methane. Nonpolar substances play an important role in a variety of biological and industrial processes, and their unique properties make them useful for many different applications.

As seen from Earth, what causes the Moon to change its apparent shape throughout the month?
Answer:
The Moon doesn't emit (give off) light itself, the 'moonlight' we see is actually the Sun's light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.

Answer:
El efecto del material sobre el medio ambiente es el aspecto a considerar.
Explicación:
Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.

If pharmaceutical researchers want to learn how to keep cancer cells from dividing uncontrollably, which
approach are they most likely to try?
Interrupt some stage of the cell cycle, such as the formation of the spindle that separates chromatids.
Develop strong dyes that will be able to color the chromosomes for good visualization.
Provide dangerous levels of radiation to irradiate the
cancer cells in a human being.
Starve the cancer cells by starving the patients, thereby reducing chances of cell division.
Answer:
c
Explanation:
Chemotherapy i.e. use of drugs to destroy the cancer cells by inhibiting their growth and division. Therefore, option (A) of interrupting stages in cell cycle is correct.
What do you understand by chemotherapy?
Chemotherapy is a medication that employs strong chemicals to destroy rapidly developing cells in your body. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. There are several chemotherapy medicines available.
Taxol (Paclitaxel) and other drugs that poison microtubules and impede the mitotic spindle have been used extremely efficiently in chemotherapy. This prevents cancer cells from proliferating and kills them.
Therefore, pharmaceutical researchers uses drugs to learn cancer treatment. Option (A) is correct.

Explain what happens at each of the following boundaries: ocean/ocean
convergent, bcean/continental convergent, continental/continental
convergent, divergent and transform plate boundaries.
Answer:
The particularly severe winter of 1777-1778 proved to be a great trial for the American army, and of the 11,000 soldiers stationed at Valley Forge, hundreds died from disease. However, the suffering troops were held together by loyalty to the Patriot cause and to General Washington, who stayed with his men.
Explanation:
Explanation:oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates.
Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed. The convergent boundaries between ocean and continental plates create subduction zones. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite.
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates. The Granite and recycled material are much lighter than the heavy basalt layers of the ocean plates.
